Arc hydro quaternary watershed sessions

The Ministry of Natural Resources and Forestry developed standardized Arc Hydro surface water data sessions based on the Quaternary Watershed fabric for the Province of Ontario. Each session contains foundation layers required for fundamental hydrologic watershed analysis.

This Arc Hydro product can be used for regional scale analysis for a variety of purposes. It is not intended for detailed site level analysis.

This data set is no longer maintained by the Ministry of Natural Resources and Forestry. The data can be accessed from the Ontario Integrated Hydrology data set.
